RIFLE TURBIN E.

Application filed November 19, 1921. Serial No. 516,465.

To all fio/"wm it may concern:

Be it known that l, OSCAR J. REN- sHAw, a citizen of the United States, residino` at Langells Valley, in the county of Klamath and State of regon, have invented certain new and useful Improvements in Rifle Turbines, of which the following is a specification, reference being had therein to the accompanying drawings.

rFhis invention relates to a rifle turbine, and has for its object the construction of a siniple and efiicient mechanism utilizing steam for rotating a piston, which piston is provided with peculiarly-constructed grooves, and which mechanism also includes an efficient valve mechanism for enabling the operation of the mechanism in an eiticient manner.

lVith this and other obj eets in view, my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a vertical, sectional view of a mechanism construct/ed in accordance with the present invention.

Figure 2 is a sectional view, taken on line 2 2, Fig.' 1* and looking in the direction of the arrows.

Figure 3 is a top, plan view of the rotary piston.

Figure 4 is a section, taken on line 4 4, Fig. 3, and looking in the direction of the arrows.

Figure 5 is a longitudinal, sectional view of another embodiment of the present invention.

Referring to the drawings by numerals, 1 designates the base structure or foundation upon which is mounted the primary casing 2. Suitable exhaust pipes 8 extend through the foundation 1 and communicate at their inner ends with the bottom of the casing 2. A. rotary7 piston 4 is mounted within the casing 2, and extending through the piston 4 is a driving shaft 5. lt is to be noted that the piston 4 is conical in shape. The lower end of the shaft 5 is provided with a ball 6, and this ball is mounted in bearing 7. A suitable packing 8 makes a tight joint around shaft 5, contiguous to the bearing 7, preventing any leaking of steam or liquid around the shaft 5.

The conical piston 4 is provided in its top `with a circular groove 9, Fig. 3, and with horizontal, V-shaped grooves 10 (ll-shaped in cross section) which grooves 10 open at their outer ends in spiral grooves 11; grooves 1 extend around the side of the rotary piston 4.

- nlet pipes 12 communicate at their inner ends with grooves 10, Fig. 1; this communication with grooves 10 is accomplished through the medium of a funnel-like construction 13 at the inner end of each inlet pipe 12, Figs. 1 and 4.

A valve seat 14 is formed in the inner end of each pipe 12, and a sliding valve 15 is in each pipe 12 and is adapted to normally seat upon valve seat 14, Fig. 1. A valve stem 16 is attached to each valve 15, and the outer end of the stem 16 extends beyond pipe 12. The outer end of each stem 1G is pivotally connected, at 17, to auxiliary rocker-arms 18; the rocker-arms 1S are pivstall;T mounted, at 19, upon brackets 20. in auxiliary casing 21 is formed upon each inlet pipe 12 and a sliding piston 22 is in each casing 21. A rod 23 is connected to each piston 22, the outer end of the rod is pivotally connected to the outer end of the auxiliary rocker-arm 18. A valve chamber 24 is provided with two hollow extensions 25, communicating with the auxiliary casing 21; in valve charnber 24 is a pair of pistons 26 fastened to valve stem 27. A by-pass 2S communicates with pipe 12 and with the valve chamber 24. Primary rocker-arms 29 are pivotally mounted, at 30, upon the frame 31 and their outer ends are pivotally connected, at 32, to the outer ends of valve stems 27 The inner ends of the primary rocker-arms 29 are pivotally connected to the collar o3, which collar 33 slidably mounted upon the primary shaft 5; this collar 33 is a part of the governor device 34, which governor device is fastened, at 35, to shaft 5.

A dynamo or any suitably driven machinery is adapted to be carried by frame 31, at 36; the driving` shaft 5 extends up into the casing 36 and is connected by any ordinary means to the machinery to be driven by my mechanism.

It is to be understood that upon live steam being discharged through the inlet pipes 12 into casing, 2 that the rotary piston will be actuated (rotated) causing the driving shaft 5 to operate the governor device 34, and the f on the inner ends of the rocker arms 29, causing the raising ofl valve stems 27 and, consequently, permitting live steam to pass in the lower hollow extensions 25, whereupon the pistons will be shoved upwardly partly closing or entirely closing valves l5 as the speed increases; upon the speed of the mechanisin decreasing the valve mechanism will be automatically operated to permit the opening' of valves l5, or a greater upward movement of said valves from their seats lll, allowing sullicient steam to enter the easing'fl and act upon the rotary piston 4 to maintain the desired speed fixed or governed by the governor device Bet.

lin-the embodiment shown in Fig. 5, l have shown what might be styled a horizontal mechanism, whereas in Fig. l l have shownavertical mechanismll; in Fig. 5 the conical piston et is in a 'horizontal position, within the casing 2. The flow of steam from the casing 2 through inlet pipes l2 is controlled by governing mechanism 37.

When this turbine is in luse the steam is turned on and passes through the pipes l2 into the groove 9 in the smaller end of the rotor fl. From the groove 9 the steam passes through the radiating` grooves l0 into the grooves ll which extend spirally about the sides of the rotor until it reaches the larger end of the rotor and passes out of the casing through the outlet pipes 3. lWhile the steam is passing through the spiral grooves 1l from the small end towards the large end of the casing and expanding during its movement it will act against the walls of the grooves and this will set up an action which will cause the rotor to be turned towards the left in Figure l. The steam will be in operative engagement with the walls of the grooves during its entire movement to the large end of the casing and there will be no abrupt rewinds. Therefore the maximum amount of power will be obtained from the steam. The governor controls the valves and opens and closes them the speed of rotation of the rotor and shaft changes and therefore the proper amountof steam will be fed into the grooves.

lVhile I have described the preferred embodiments of my invention, and have illustrated the same 'in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and Ltherefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.
